Acetone vs. Mineral Spirits — What's the Difference?
By Urooj Arif & Maham Liaqat — Published on July 31, 2024
Acetone is a fast-evaporating, highly volatile solvent used for thinning and cleaning, especially in nail polish removal. Mineral spirits, less volatile, are used for thinning oil-based paints and cleaning brushes, offering a milder alternative.

Key Differences
Acetone, a solvent found in many household and industrial products, is known for its effectiveness in breaking down and dissolving substances like nail polish, making it a popular choice in cosmetics and painting industries. Its high volatility means it evaporates quickly, leaving little residue but requiring careful handling due to its flammability and strong odor.
Mineral spirits, also known as white spirit, are derived from petroleum and have a much slower evaporation rate compared to acetone. This characteristic makes them ideal for thinning oil-based paints and varnishes, as well as for cleaning brushes and tools used in painting. Their less volatile nature results in a milder odor and reduced flammability, making them safer for prolonged use in less ventilated areas.
Acetone's quick evaporation rate is advantageous for tasks requiring rapid drying, this property also makes it more hazardous in terms of flammability and potential health effects from inhalation. Its effectiveness as a solvent for plastics and synthetic fibers, however, is unmatched by mineral spirits.
Mineral spirits, being less aggressive than acetone, are preferred for delicate cleaning tasks and for thinning paints where a slower drying time is beneficial. This solvent is less likely to damage surfaces or remove finishes, making it suitable for a wide range of materials and applications in woodworking and painting.
The choice between acetone and mineral spirits depends on the specific needs of the task at hand. Acetone is best suited for quick, aggressive cleaning and thinning tasks, while mineral spirits are better for slower, more controlled applications where surface preservation is key.

Common Curiosities
Can I use mineral spirits on plastic?
Mineral spirits are generally safer on plastics than acetone, but testing on an inconspicuous area is recommended to avoid damage.
Can mineral spirits be used instead of acetone?
Yes, but with different outcomes due to their varying evaporation rates and solvent strengths.
Are mineral spirits safe for all paint types?
Mineral spirits are suitable for oil-based paints but not for water-based paints, as they can affect the paint's consistency and drying time.
Are acetone and mineral spirits interchangeable?
They are not directly interchangeable; each solvent serves specific purposes based on its properties.
Is acetone more effective than mineral spirits?
Acetone is more effective for certain tasks like removing nail polish or dissolving plastics, whereas mineral spirits are better for thinning paints and cleaning brushes without damaging the material.
Can mineral spirits be used on wood?
Yes, mineral spirits can be used to clean wood surfaces, remove grime, or prepare the surface for finishing.
What precautions should be taken when using acetone?
Use acetone in well-ventilated areas, wear gloves and eye protection, and keep it away from open flames.
How do I dispose of acetone or mineral spirits?
Both should be disposed of according to local hazardous waste disposal regulations to prevent environmental harm.
Is there an odorless alternative to mineral spirits?
Odorless mineral spirits are available, which are refined to remove the aromatic solvents, reducing the odor.
Can acetone remove paint?
Yes, acetone can remove certain types of paint, especially if they are fresh or not fully cured.
